In 2005, James Fallon’s life started to resemble the plot of a well-honed joke or big-screen thriller: A neuroscientist is working in his laboratory one day when he thinks he has stumbled upon a big mistake. He is researching Alzheimer’s and using his healthy family members’ brain scans as a control, while simultaneously reviewing the fMRIs of murderous psychopaths for a side project. It appears, though, that one of the killers’ scans has been shuffled into the wrong batch.
Weight-loss surgery may be an option if you are very obese and have not been able to lose weight through diet and exercise. However, these surgeries are not a “quick fix” for obesity. You must still committed to diet and exercise after the surgery. Talk to your doctor to learn if this is a good option for you.
Measuring a person’s body fat percentage can be difficult, so other methods are often relied upon to diagnose obesity. Two widely used methods are weight-for-height tables and body mass index (BMI). While both measurements have their limitations, they are reasonable indicators that someone may have a weight problem. The calculations are easy, and no special equipment is required.
Gallup data indicate that more than half (53%) of today’s baby boomers (U.S. adults aged 39 to 57) perceive themselves to be either “very” or “somewhat” overweight. This percentage is significantly higher than it is for either the 18- to 39-year-old cohort (30%) or the 75+ year-old cohort (30%), although it is very similar to the percentage for the 58- to 74-year-old category (56%).
Differences in gastrointestinal bacteria may contribute to overweight and obesity. NHLBI and other partners in the Trans-NIH Microbiome Working Group are investigating how different populations of bacteria in our gastrointestinal tracts may make people resistant or susceptible to obesity.

At what stage of life a person becomes obese can affect his or her ability to lose weight. In childhood, excess calories are converted into new fat cells (hyperplastic obesity), while excess calories consumed in adulthood only serve to expand existing fat cells (hypertrophic obesity). Since dieting and exercise can only reduce the size of fat cells, not eliminate them, persons who were obese as children can have great difficulty losing weight, since they may have up to five times as many fat cells as someone who became overweight as an adult.

The program should provide long-term strategies for dealing with weight problems that may come up in the future. These strategies might include things like establishing a support system and establishing a physical activity routine.
In 2004, the United Kingdom Royal College of Physicians, the Faculty of Public Health and the Royal College of Paediatrics and Child Health released the report “Storing up Problems”, which highlighted the growing problem of obesity in the UK.[159] The same year, the House of Commons Health Select Committee published its “most comprehensive inquiry […] ever undertaken” into the impact of obesity on health and society in the UK and possible approaches to the problem.[160] In 2006, the National Institute for Health and Clinical Excellence (NICE) issued a guideline on the diagnosis and management of obesity, as well as policy implications for non-healthcare organizations such as local councils.[161] A 2007 report produced by Derek Wanless for the King’s Fund warned that unless further action was taken, obesity had the capacity to cripple the National Health Service financially.[162]
We help obese individuals determine whether surgery is a good option and help WLS patients find the right surgical team and set, achieve and maintain specific and realistic health and weight loss goals.

Body Mass Index (BMI) is a mathematical calculation involving height and weight, irrespective of family history, gender, age or race. BMI is calculated by dividing a person’s body weight in kilograms by their height in meters squared (weight [kg] height [m]2) or by using the conversion with pounds (lbs) and inches (in) squared as shown below, This number can be  misleading, however, for very muscular people, or for pregnant or lactating women.
Roughly 35% of Americans age 65 years old and older were obese at the end of 2010, representing more than 13 million people (4), according to the Centers for Disease Control and Prevention (CDC). The total population of seniors is expected to swell in the coming years to 88.5 million people by 2050 from 40.2 million in 2010, according to CDC data.

I’m not picking out rare, less healthy examples from these establishments. Check out their menus online: fat, sugar, and other refined carbs abound. (Café Gratitude says it uses only “healthy” fats and natural sweeteners; Akasha says its focus is not on “health food” but on “farm to fork” fare.) In fact, because the products and dishes offered by these types of establishments tend to emphasize the healthy-sounding foods they contain, I find it much harder to navigate through them to foods that go easy on the oil, butter, refined grains, rice, potatoes, and sugar than I do at far less wholesome restaurants. (These dishes also tend to contain plenty of sea salt, which Pollanites hold up as the wholesome alternative to the addictive salt engineered by the food industry, though your body can’t tell the difference.)
While losing weight is a simple concept in theory — expend more calories than you take in — it is a more complex process in reality. But for seniors, the “battle of the bulge” can be even harder to the natural slowing down of the metabolism. In other words, a 65-year-old might eat the same meal he ate at age 20 and yet burn calories at a slower rate. This can be confusing and frustrating for seniors as they watch the pounds creep up on the scale.
